Microstructure properties of lead silicate glasses

Abstract EN

In the present work, lead silicate glasses have been prepared with different amount of lead oxide content.

Structure properties such as X-ray diffraction, AFM, and FTIR analyses have been done.

The exceeding of PbO content more than 25wt% revealed a decreasing in density.

The X- ray revealed that the strongest peak related to Hexagonal silica dioxide and the other crystal phases formed were related to silica oxide (SiO2) and lead oxide (PbO).

Growth and decayed phases in X-ray have been observed with changing lead oxide content.

Homogeneous surface was obtained using AFM analyzer with an average diameter around 100 nm.

Infrared spectrum is characterized by the presence of large absorption band between 1200 and 900cm-1 and have its maximum at 1080 cm-1 which is typical to stretching vibrations of Si–O–Si bonds, another bands noticed were attributed to Pb–O–Pb, Pb–O–Si, [AlO4]-tetrahedron, and to Si–O–Al bond.
